Abstract
Abstract Hexa-2,4-dienal condensed with (-)-ephedrine to give predominantly the oxazolidine 4 , which underwent a stereoselective Diels-Alder reaction with benzyl nitrosoformate to give the cycloadducts 9 and 10 in a ca 5:2 ratio. Further transformations of 9 to give the optically active mono- and tri- hydroxypiperidine derivatives 11 and 15 have also been performed.
